Abstract
Système de multitraitement de données. La présente invention concerne un système de multitraitement de données comportant une pluralité de processeurs, une unité principale mémoire mémorisant au moins une ressource commune utilisée exclusivement par un processeur, et mémorisant des mots d'état d'utilisation pour indiquer les états utilisables ou non utilisables de la ressource commune et mémorisés correspondant à la ressource commune dans l'unité principale de mémoire, où un processeur réécrit le contenu du mot d'état d'utilisation lu dans l'état non utilisable lorsqu'un mot d'état d'utilisation lu indique l'état utilisable de la ressource commune, alors que le processeur est empêché d'utiliser la ressource commune correspondant au mot d'état lorsqu'un mot d'état d'utilisation lu indique l'état non utilisable de la ressource commune Application aux systèmes de multitraitement de données.Data multiprocessing system. The present invention relates to a data multiprocessing system comprising a plurality of processors, a main memory unit storing at least one common resource used exclusively by a processor, and storing use status words to indicate usable or unusable states. of the common resource and stored corresponding to the common resource in the main memory unit, where a processor rewrites the contents of the read usage state word in the non-usable state when a usage state word lu indicates the usable state of the common resource, while the processor is prevented from using the common resource corresponding to the status word when a usage status word read indicates the unusable state of the common resource Application to multiprocessing data systems.
